DE   D-apionate oxidoisomerase.
CA   D-apionate + NAD(+) = 3-oxoisoapionate + H(+) + NADH.
CC   -!- The enzyme, characterized from several bacterial species,
CC       participates in the degradation of D-apionate.
CC   -!- The reaction involves migration of a hydroxymethyl group from
CC       position 3 to position 2 and oxidation of the 3-hydroxyl group.
CC   -!- Stereospecificity of the product, 3-oxoisoapionate, has not been
CC       determined.
